It’s long been established that breathing polluted air can have negative effects on our physical wellbeing—such as lung and heart diseases, cancer, even death—but it can also have consequences on our mental health. Researchers compared 20,000 Chinese citizens’ performance on language and arithmetic tests conducted between 2010 and 2014 with recorded levels of local nitrogen dioxide and sulfur dioxide pollution, The Guardian reports. High pollution levels were linked to significant drops in test scores, with the average impact equivalent to having lost a year of the person’s education, the scientists report this week in the Proceedings of the National Academy of Sciences. The drop in test performance was greater for men, individuals over the age of 64, and people with less education.

But this doesn't surprise me at all. I've really noticed people are getting more stupid as the years go by, and of course another big reason is the less nutritious food as we deplete the soil, mono crops like corn and soy, and use chemical fertilizers. It's why I really want people to learn wild plants, and eating nuts and seeds, sunlower seeds especially because of the lecithin, and eating free black walnuts from the woods, high in omega 3 fats, and the leaves that I learned here from MH - and Dr. John Ray Christopher, are high in natural iodine, which are both extremely important for brain function.

I've been finding a lot more hickory nut trees this year, I'm trying to beat the squirrels to them.

Also, there's a lot of omega 3 fats in a wild plant called purslane, and according to the USDA website, it is in every state, considered noxious and invasive. Also, the fat is in regular mustard seeds. There's an invasive mustard originally from Europe called garlic mustard, it's in most of the lower forty eight states. https://plants.usda.gov/core/profile?symbol=alpe4 Tweet
